RELATED APPLICATION DATA

This application is a continuation of U.S. patent application Ser. No.13/414,809 filed Mar. 8, 2012, the entirety of which is incorporatedherein by reference to the extent permitted by law. The presentapplication claims the benefit of priority to Japanese PatentApplication No. JP 2011-068154 filed on Mar. 25, 2011 in the JapanPatent Office, the entirety of which is incorporated by reference hereinto the extent permitted by law.

BACKGROUND

The present disclosure relates to a display panel capable of multi-viewdisplaying that allows visual recognition of two-dimensional video(planar video) that differs for each point of view or three-dimensionaldisplaying that allows visual recognition of three-dimensional video(stereoscopic video) from a specific point of view. Furthermore, thepresent disclosure relates to a display device including this displaypanel and electronic apparatus including this display device.

In recent years, display devices capable of multi-view displaying orthree-dimensional displaying have been put into practical use. As one ofsuch display devices, e.g. a display device having a barrier layer overthe display area of a display panel is known. As one of such barrierlayers, a barrier layer in which plural light transmissive slitsisolated from each other by a light blocking area are provided isdisclosed in Japanese Patent Laid-open No. Hei 9-281440 for example.Furthermore, a barrier liquid crystal in which a light blocking area isgenerated by voltage application to a liquid crystal is disclosed inJapanese Patent Laid-open No. Hei 8-106070 for example.

SUMMARY

If the above-described barrier layer is provided, light leakage readilyoccurs from the periphery of the barrier layer. As a countermeasureagainst this problem, covering the periphery of the barrier layer by themetal frame of the chassis will be possible for example. To obtain thisstructure, the edge of the display area, in which plural display pixelsare two-dimensionally disposed, needs to be precisely aligned with theedge of the metal frame. However, for this precise alignment,positioning of the metal frame needs to be performed at the pixel-sizelevel. Therefore, slight dimensional error or position misalignment ofthe metal frame leads to a possibility that the metal frame covers thedisplay pixel.

In addition, a method of enlarging the outer periphery of the barrierlayer to the area where light leakage occurs to prevent the lightleakage will be possible for example. Normally, the metal frame has asize somewhat larger than the display area in view of dimensional errorand position misalignment. Therefore, if the outer periphery of thebarrier layer is enlarged as described above, the light blocking area ofthe barrier layer is located between the metal frame and the displayarea and thus the light blocking area often looks like a black streak.In particular, if the metal frame is decorated with a bright color suchas white, this black streak is conspicuous and is possibly regarded asdisplaying failure.

The present disclosure has been made in order to solve the problemsdescribed above, and it is therefore desirable to provide a displaypanel capable of making the black streak inconspicuous, and displaydevice and electronic apparatus including it.

According to an embodiment of the present disclosure, there is provideda display panel including a panel section and a barrier section disposedat a position opposed to the panel section. The panel section has adisplay area in which a plurality of display pixels aretwo-dimensionally disposed and a ring-like frame area provided at theperiphery of the display area. The barrier section has a barrier patterncomposed of a light blocking area and a light transmissive area. Boththe light blocking area and the light transmissive area are disposed ina first area opposed to the display area and a ring-like second areaopposed to the frame area.

According to another embodiment of the present disclosure, there isprovided a display device including the above-described display paneland a drive section that drives at least the panel section out of thepanel section and the barrier section. According to another embodimentof the present disclosure, there is provided electronic apparatusincluding the above-described display device.

In the display panel, the display device, and the electronic apparatusaccording to the embodiments of the present disclosure, both the lightblocking area and the light transmissive area of the barrier section aredisposed in not only the first area opposed to the display area but alsothe ring-like second area opposed to the frame area. Due to thisfeature, in not only the display area but also the frame area, the lightblocking area included in the barrier pattern is disposed and the lighttransmissive area included in the barrier pattern is disposed. As aresult, light that is unnecessary for displaying is blocked by the lightblocking area included in the barrier pattern in not only the displayarea but also the frame area. Furthermore, light transmitted through thelight transmissive area included in the barrier pattern is output fromnot only the display area but also the frame area.

In the display panel, the display device, and the electronic apparatusaccording to the embodiments of the present disclosure, the lighttransmissive area is formed of e.g. a plurality of light transmissiveslits. In this case, the plurality of light transmissive slits aredisposed regularly as a whole, and the respective light transmissiveslits have the same shape and the same size for example.

The light transmissive area is disposed at places corresponding to theleft and right sides of the display area in the second area for example.Furthermore, according to need, the light transmissive area may bedisposed also at places corresponding to the upper and lower sides ofthe display area in the second area. Part of the plurality of lighttransmissive slits may be disposed in only the second area in such amanner as not to range over the first area. Furthermore, all or part ofthe plurality of light transmissive slits may be so disposed as tostraddle both the first area and the second area.

The display area has e.g. a rectangular shape having four sides. In thiscase, the light blocking area may be formed of a plurality of lightblocking slits extended along a direction parallel to one side of thedisplay area or may be formed of a plurality of light blocking slitsextended along a direction intersecting one side of the display area.Alternatively, the light blocking area may be formed of a plurality oflight blocking slits that are arranged along a first directionintersecting one side of the display area and are arranged also along asecond direction intersecting the first direction.

The barrier section may have a light blocking component in the lightblocking area and have an aperture in the light transmissive area.Furthermore, the barrier section may be capable of controlling anoptical characteristic of the light blocking area based on a controlsignal from the external.

In the display panel, the display device, and the electronic apparatusaccording to the embodiments of the present disclosure, light that isunnecessary for displaying is blocked by the light blocking areaincluded in the barrier pattern in not only the display area but alsothe frame area. Furthermore, light transmitted through the lighttransmissive area included in the barrier pattern is output from notonly the display area but also the frame area. Therefore, the blackstreak can be made inconspicuous with prevention of light leakage thatleads to displaying failure.

If the light transmissive area is disposed at not only the placescorresponding to the left and right sides of the display area but alsothe places corresponding to the upper and lower sides of the displayarea in the second area in the embodiments of the present disclosure,the black streak can be made inconspicuous with prevention of lightleakage that leads to displaying failure also when the display panel isso used as to be rotated by 90 degrees for example.

Embodiment [Configuration]

FIG. 1A shows one example of the sectional configuration of a displaydevice 1 according to one embodiment of the present disclosure. FIG. 1Bshows one example of the upper surface configuration of the displaydevice 1 of FIG. 1. FIGS. 1A and 1B are schematic diagrams and thedimensions and shapes in these diagrams are not necessarily the same asthe actual dimensions and shapes. The display device 1 includes adisplay panel 20 and a backlight 10 disposed on the back side of thedisplay panel 20. This display device 1 further includes a chassis 50that houses the display panel 20 and the backlight 10, and a drivesection (not shown) that drives the display panel 20 (specifically, apanel section 30 to be described later).

The backlight 10 is a surface emission source that illuminates thedisplay panel 20 from the back side. The chassis 50 has an aperture 50Aat the part opposed to the upper surface of the display panel 20 as avideo display surface 1A. The edge of the aperture 50A is disposed inthe area opposed to a frame area 30B to be described later. The displaypanel 20 has the panel section 30 and a barrier section 40. The uppersurface of the display panel 20 serves as the video display surface 1Aand the barrier section 40 is disposed at the surface on the side of thevideo display surface 1A.

The panel section 30 is a transmissive panel in which the respectivedisplay pixels 31 (see FIG. 1B to be described later) are driven inaccordance with a video signal input from the external. The panelsection 30 is e.g. a liquid crystal panel, an organicelectro-luminescence (EL) panel, or a plasma panel. The panel section 30has e.g. a rectangular shape having four sides as shown in FIG. 1B. Thefollowing various descriptions are based on the assumption that twosides opposed to each other among four sides of the panel section 30 areoriented in the horizontal direction and the remaining two sides areoriented in the vertical direction.

The panel section 30 has a display area 30A in which the plural displaypixels 31 are two-dimensionally disposed, and the ring-like frame area30B at the periphery of the display area 30A. The display area 30A hase.g. a rectangular shape having four sides similarly to the panelsection 30 as shown in FIG. 1B. Hereinafter, the partial places of theframe area 30B opposed to each other in the horizontal direction(left-right direction of FIG. 1B) with the intermediary of the displayarea 30A will be referred to as the partial area 30C. Furthermore, thepartial places of the frame area 30B opposed to each other in thevertical direction (upward-downward direction of FIG. 1B) with theintermediary of the display area 30A will be referred to as the partialarea 30D.

The frame area 30B can be divided into two areas based on therelationship with the aperture 50A of the chassis 50. For example, asshown in FIG. 1B, the frame area 30B is composed of a ring-like frameexposed area 30B-1 exposed in the aperture 50A and a ring-like framecovered area 30B-2 covered by the chassis 50. The frame exposed area30B-1 is disposed on the side of the display area 30A and the framecovered area 30B-2 is disposed at the periphery of the frame exposedarea 30B-1. The frame area 30B is covered by a black 33 having lightblocking capability as shown in FIG. 4 to be described later. The black33 is disposed also among the display pixels 31 for example although notshown in the diagram.

Each display pixel 31 provided in the display area 30A is composed ofplural sub-pixels 32. For example, as shown in FIG. 1B, the displaypixel 31 is composed of a sub-pixel 32R for red, a sub-pixel 32G forgreen, and a sub-pixel 32B for blue. The sub-pixels 32R of therespective display pixels 31 are disposed on one row along the verticaldirection (upward-downward direction of FIG. 1B) for example. Similarly,the sub-pixels 32G of the respective display pixels 31 are also disposedon one row along the vertical direction (upward-downward direction ofFIG. 1B) for example, and the sub-pixels 32B of the respective displaypixels 31 are also disposed on one row along the vertical direction(upward-downward direction of FIG. 1B) for example. That is, thesub-pixels 32R, 32G, and 32B are based on a so-called stripe array. Thekinds and number of colors of the sub-pixels 32 included in the displaypixel 31 are not limited to the above description. The array of thesub-pixels 32R, 32G, and 32B is also not limited to the abovedescription.

The barrier section 40 blocks part of light (image light) output fromthe respective display pixels 31 of the panel section 30. The barriersection 40 is to allow the viewer to visually recognize two-dimensionalvideo (planar video) that differs for each point of view or visuallyrecognize three-dimensional video (stereoscopic video) from a specificpoint of view by blocking part of the image light. If the barriersection 40 is so configured that the viewer can visually recognizetwo-dimensional video (planar video) that differs for each point ofview, the display device 1 serves as a so-called multi-view displaydevice. If the barrier section 40 is so configured as to allow visualrecognition of three-dimensional video (stereoscopic video) from aspecific point of view, the display device 1 serves as athree-dimensional video display device.

For example, as shown in FIG. 2, the barrier section 40 is disposed at aposition opposed to the panel section 30 and has a barrier patterncomposed of light blocking slits 40A and light transmissive slits 40B.The light blocking slit 40A is equivalent to one specific example of thelight blocking area set forth in the scope of claims. The lighttransmissive slit 40B is equivalent to one specific example of the lighttransmissive area set forth in the scope of claims.

Each light blocking slit 40A is formed of e.g. a light blockingcomponent. The plural light blocking slits 40A are disposed regularly asa whole. The respective light blocking slits 40A have the same shape andthe same size as shown in FIG. 2 for example. Each light transmissiveslit 40B is e.g. an aperture. The plural light transmissive slits 40Bare disposed regularly as a whole. The respective light transmissiveslits 40B have the same shape and the same size as shown in FIG. 2 forexample.

For example, as shown in FIG. 2, the plural light blocking slits 40A areextended along the upward-downward direction (vertical direction) ofFIG. 2 and disposed on one row along the left-right direction(horizontal direction) of FIG. 2. Similarly, the light transmissiveslits 40B are extended along the upward-downward direction (verticaldirection) of FIG. 2 and disposed on one row along the left-rightdirection (horizontal direction) of FIG. 2 as shown in FIG. 2 forexample. Each light blocking slit 40A is so disposed as not to straddleboth the display area 30A and the frame area 30B. That is, some lightblocking slits 40A are disposed in only the display area 30A, and theother light blocking slits 40A are disposed in only the frame area 30B.In contrast, some light transmissive slits 40B are so disposed as not tostraddle both the display area 30A and the frame area 30B, and the otherlight transmissive slits 40B are so disposed as to straddle both thedisplay area 30A and the frame area 30B. The light blocking slits 40Aand the light transmissive slits 40B are alternately disposed in thearrangement direction as shown in FIG. 2 for example.

All light blocking slits 40A do not need to have the same shape and thesame size. For example, as shown in FIG. 3, only one or plural lightblocking slits 40A at both ends of the arrangement direction among theplural light blocking slits 40A may have a width wider than that of theother light blocking slits 40A. That is, the respective light blockingslits 40A may have various shapes and sizes within such a range that therespective light transmissive slits 40B have the same shape and the samesize.

FIG. 4 schematically shows one example of the sectional configurationalong the direction of arrow A-A in FIG. 2. The light blocking slits 40Aand the light transmissive slits 40B are disposed in the area opposed tothe display area 30A and the ring-like area opposed to the frame area30B as shown in FIGS. 2 to 4. That is, the light blocking slits 40A andthe light transmissive slits 40B are disposed in not only the areaopposed to the display area 30A but also the ring-like area opposed tothe frame area 30B.

The light blocking slits 40A and the light transmissive slits 40B aredisposed in the area opposed to the display area 30A and at placescorresponding to the left and right sides of the display area 30A (i.e.partial areas 30C) in the ring-like area opposed to the frame area 30B.The light blocking slits 40A and the light transmissive slits 40B areformed in both the frame exposed area 30B-1 and the frame covered area30B-2 as shown in FIG. 4.

One light blocking slit 40A is formed in each of the right-side frameexposed area 30B-1 and the left-side frame exposed area 30B-1 as shownin FIG. 4 for example. As shown in FIG. 5, two or more light blockingslits 40A may be formed in each of the right-side frame exposed area30B-1 and the left-side frame exposed area 30B-1 for example. One lightblocking slit 40A is formed in each of the right-side frame covered area30B-2 and the left-side frame covered area 30B-2 as shown in FIG. 4 forexample. As shown in FIG. 6, the light blocking slit 40A may be absentin the right-side and left-side frame covered area 30B-2 for example.Although not shown in the diagram, two or more light blocking slits 40Amay be formed in each of the right-side frame covered area 30B-2 and theleft-side frame covered area 30B-2 for example.

The light transmissive slit 40B is so formed as to straddle the displayarea 30A and the frame exposed area 30B-1 as shown in FIG. 4 forexample. Furthermore, the light transmissive slit 40B is so formed as tostraddle the frame exposed area 30B-1 and the frame covered area 30B-2as shown in FIG. 4 for example. As shown in FIG. 7, the light blockingslit 40A may be so formed as to straddle the frame exposed area 30B-1and the frame covered area 30B-2 for example. In this case, the lighttransmissive slit 40B may be formed in the frame exposed area 30B-1 soas not to straddle the frame exposed area 30B-1 and the frame coveredarea 30B-2.

[Operation]

In the present embodiment, light output from the backlight 10 ismodulated by the respective display pixels 31 of the panel section 30and predetermined image light is output to the barrier section 40. Then,part of the image light is blocked by the light blocking slits 40A ofthe barrier section 40 and light transmitted through the lighttransmissive slits 40B is output from the video display surface 1A ofthe display panel 20. The light output from the video display surface 1Aforms images at plural points of view for example, so thattwo-dimensional video (planar video) is generated. Alternatively, thelight output from the video display surface 1A forms an image at aspecific point of view for example, so that three-dimensional video(stereoscopic video) is generated.

[Effects]

In the present embodiment, both the light blocking slit 40A and thelight transmissive slit 40B of the barrier section 40 are disposed innot only the area opposed to the display area 30A but also the ring-likearea opposed to the frame area 30B. Due to this feature, in not only thedisplay area 30A but also the frame area 30B, the light blocking slit40A included in the barrier pattern is disposed and the lighttransmissive slit 40B included in the barrier pattern is disposed. As aresult, light that is unnecessary for displaying is blocked by the lightblocking slit 40A included in the barrier pattern in not only thedisplay area 30A but also the frame area 30B. Furthermore, lighttransmitted through the light transmissive slit 40B included in thebarrier pattern is output from not only the display area 30A but alsothe frame area 30B. Therefore, the black streak can be madeinconspicuous with prevention of light leakage that leads to displayingfailure.

2. Modification Examples First Modification Example

In the above-described embodiment, each light blocking slit 40A isformed of e.g. a light blocking component and each light transmissiveslit 40B is e.g. an aperture. That is, the barrier section 40 is basedon a static configuration. However, the barrier section 40 may be basedon a dynamic configuration in which the optical characteristics of thelight blocking slit 40A can be controlled based on a control signal fromthe external.

The barrier section 40 has e.g. a pair of transparent electrodesubstrates formed of glass or the like including a transparentelectrode, and a pair of polarizing plates provided outside the pair oftransparent electrode substrates. The pair of transparent electrodesubstrates have alignment films for which alignment treatment isperformed in a predetermined direction on their surfaces opposed to eachother. The barrier section 40 has a liquid crystal layer between thepair of transparent electrode substrates. The barrier section 40 has thetransparent electrode at the place corresponding to the light blockingslit 40A and has a transparent electrode that can be drivenindependently of the former transparent electrode also at the placecorresponding to the light transmissive slit 40B. In this manner, in thepresent modification example, the barrier section 40 is based on adynamic configuration and therefore the drive section drives not onlythe panel section 30 but also the barrier section 40.

Except for that the barrier section 40 is based on a dynamicconfiguration, the present modification example has the sameconfiguration as that of the above-described embodiment regarding theremaining part. Therefore, as with the above-described embodiment, theblack streak can be made inconspicuous with prevention of light leakagethat leads to displaying failure.

Second Modification Example

In the above-described embodiment, the barrier pattern is extended alongthe vertical direction. However, it may be extended along an obliquedirection for example. For example, as shown in FIG. 8, the lightblocking slit 40A and the light transmissive slit 40B may be extendedalong a direction intersecting the vertical direction (i.e. obliquedirection). FIG. 8 shows one example of the planar configuration of thebarrier section 40 according to the present modification exampletogether with the panel section 30.

In the present modification example, part of the light blocking slits40A is so disposed as to straddle both the display area 30A and theframe area 30B. Similarly, part of the light transmissive slits 40B isalso so disposed as to straddle both the display area 30A and the framearea 30B.

Also in the present modification example, as with the above-describedembodiment, light that is unnecessary for displaying is blocked by thelight blocking slit 40A included in the barrier pattern in not only thedisplay area 30A but also the frame area 30B. Furthermore, lighttransmitted through the light transmissive slit 40B included in thebarrier pattern is output from not only the display area 30A but alsothe frame area 30B. Therefore, the black streak can be madeinconspicuous with prevention of light leakage that leads to displayingfailure.

Third Modification Example

In the above-described embodiment, the barrier pattern is extended alongthe vertical direction or an oblique direction. However, e.g. a stepbarrier pattern may be employed. The step barrier pattern refers to e.g.a pattern in which, as shown in FIG. 9, the plural light transmissiveslits 40B are arranged along a direction intersecting one side of thedisplay area 30A (or the panel section 30) and arranged also along adirection intersecting this arrangement direction. FIG. 9 shows oneexample of the planar configuration of the barrier section 40 accordingto the present modification example together with the panel section 30.

Also in the present modification example, as with the above-describedembodiment, light that is unnecessary for displaying is blocked by thelight blocking slit 40A included in the barrier pattern in not only thedisplay area 30A but also the frame area 30B. Furthermore, lighttransmitted through the light transmissive slit 40B included in thebarrier pattern is output from not only the display area 30A but alsothe frame area 30B. Therefore, the black streak can be madeinconspicuous with prevention of light leakage that leads to displayingfailure.

Fourth Modification Example

In the above-described second modification example and thirdmodification example, the light blocking slit 40A and the lighttransmissive slit 40B may be disposed in not only the display area 30Aand the partial area 30C but also the partial area 30D as shown in FIGS.10 to 13 for example. FIG. 10 shows one modification example of theplanar configuration of the barrier section 40 according to theabove-described second modification example. FIG. 11 shows one exampleof the sectional configuration along the direction of arrow A-A in FIG.10. FIG. 12 shows one modification example of the planar configurationof the barrier section 40 according to the above-described thirdmodification example. FIG. 13 shows one example of the sectionalconfiguration along the direction of arrow A-A in FIG. 12.

Like in the present modification example, the light blocking slit 40Aand the light transmissive slit 40B may be disposed in the display area30A and the partial areas 30C and 30D. In this case, for example alsowhen the panel section 30 is so used as to be rotated by 90 degrees, theblack streak can be made inconspicuous with prevention of light leakagethat leads to displaying failure.

Fifth Modification Example

In the above-described embodiment and first to fourth modificationexamples, the barrier section 40 may be disposed under the panel section30 (i.e. between the panel section 30 and the backlight 10) as shown inFIG. 14 for example. Also in this case, the black streak can be madeinconspicuous with prevention of light leakage that leads to displayingfailure.

3. Application Example
